Tracing the Dynamic Chemical Transformations of Spiro‐OMeTAD in Operating Perovskite Solar Cells

open access: yesAdvanced Science, EarlyView.
Mapping of Spiro‐OMeTAD layer's chemistry and electronic properties in PSC: Advanced cluster ion‐beam sputtering depth profile XPS reveals that environmental stressors (light, potential, and moisture) trigger the decomposition of LiTFSI dopants in Spiro‐OMeTAD.

Tailored Catalytic Microenvironments Enable Efficient Electrochemical Ammonia Production

open access: yesAdvanced Science, EarlyView.
This study shows that Co2+ substitution in inverse spinel FeFeCoO4 constructs an integrated catalytic microenvironment for efficient nitrate‐to‐ammonia reduction. Jahn–Teller distortion activates Fe sites for *H generation, while hard–soft acid–base regulated dual‐metal sites optimize proton‐coupled electron transfer and intermediate adsorption ...

Faster and Durable: A Cell‐to‐System Validation of a Low‐Degradation Fast‐Charge Protocol for Li‐Ion Batteries

open access: yesAdvanced Science, EarlyView.
A physics‐based framework resolving graphite phase‐separation dynamics establishes a predictive, degradation‐aware fast‐charging methodology for commercial Li‐ion batteries. The resulting model‐informed protocol achieves 20%–80% state‐of‐charge in 14 min while matching the long‐term degradation of a commercial 25‐minute EV strategy.
